Abstract
Preassembled drainage line units for a septic tank nitrification field employ a predetermined length of perforated conduit having an aggregation of discrete, crush resistant, light-weight elements surrounding the length of conduit and a perforated sleeve member enveloping the aggregation and bounding the same relative to the conduit with the ends of the conduit extending beyond the sleeve. The drainage line unit is provided with connecting means at each extending end, for end-to-end interconnection with an adjacent drainage line unit.
